Richard has a bag of blocks. Without looking in the bag, he selects a block, records its color, and puts it back in the
bag. All blocks are equally likely to be chosen. He performs
the process 50 times. In the 50 trials, he records the
following colors of blocks from the bag.
12
Number of times a yellow block was chosen
Number of times a red block was chosen
11
Number of times a green block was chosen
16
Number of times a blue block was chosen
5
Number of times a orange block was chosen 6
Based on the data Richard collected, what is the estimated probability, in
simplest form, of choosing a green block from the bag?

Which statements about tornadoes are true? check all that apply. (a) about 12,000 tornadoes hit the united states every year. (b) a tornado looks like a funnel. (c) tornadoes are deadly atmospheric storms that cause millions in damages each year. (d) tornadoes can reach wind speeds of more than 300 miles per hour. (e) kansas is the state with the most tornadoes. (f) you will always notice a funnel before a tornado strikes.

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.
